Fergie was “hallucinating on a daily basis” during her battle with drugs.
The ‘Big Girls Don’t Cry’ hitmaker admits she was suffering from a “chemically induced psychosis” when she used to take crystal meth.
She said: “I was [suffering from] chemically induced psychosis and dementia.
I was hallucinating on a daily basis. It took a year after getting off that drug for the chemicals in my brain to settle so that I stopped seeing things. I’d just be sitting there, seeing a random bee or bunny.”
And the 42-year-old singer – who is now clean of the substances – admits at one point that she thought she was being tracked by the CIA and FBI.
Speaking about how she was convinced that “the CIA, FBI and a SWAT team” were tracking her, so she tried to hide at a church, she added: “They tried to kick me out, because I was moving down the aisles in this crazy way, as I thought there was an infrared camera in the church trying to check for my body. I bolted past the altar into a hallway and two people were chasing me.
